Validate a file's mime-type.
use Jstewmc\ValidateFileType\Validate;
// create a txt file
$txtFilename = '/path/to/foo.txt';
$txtContents = 'foo';
file_put_contents($txtFilename, $txtContents);
// create an xml file
$xmlFilename = '/path/to/foo.xml';
$xmlContents = '<?xml version="1.0" encoding="UTF-8"?><foo />';
file_put_contents($xmlFilename, $xmlContents);
// create a service to validate text files
$service = new Validate(['text/plain']);
// validate our two files
$service($txtFilename); // returns true
$service($xmlFilename); // returns falseThis library uses PHP's fileinfo extension to look for certain magic byte sequences in a file to guess it's type. While this is not a bulletproof approach, the heuristics used do a very good job.
That's it!
